The SPA2 Automates a Sewage Treatment Sludge Pump Application

The SPA2 Automates a Sewage Treatment Sludge Pump Application

A sewage treatment plant needed to automate the start-stop of a large pump/grinder motor. The existing application used a tank level meter to signal the start-stop of the motor. However human intervention was frequently required to manually override the motor stop mechanism to allow it to continue to operate after the tank was emptied to assure the grinder portion was clear of old debris that would cause a possible stall on the next start. See how the SPA2 helped solve this problem.

EHELP: Alarm Tank Level Changes with the SPA2

EHELP: Alarm Tank Level Changes with the SPA2
Q: I want to install a 4-20mA pressure transducer that shows the tank level with an alarm to alert if it is outside the controlled level. With the same signal I want to display the level, alert of level loss, and shut down the pumps if the level reaches a critical point.

STA Aids in Functional Safety Coal Gas Extraction Application Down Under

STA Aids in Functional Safety Coal Gas Extraction Application Down Under

Moore Industries-Pacific recently sold 221 STA Safety Trip Alarms to be used in a Functional Safety coal gas extraction application in Australia. A Coal Seam Gas exploration company with hundreds of sites in Queensland has production wells with up to 10 inputs controlled locally by Remote Terminal Units (RTUs). The STA will be implemented as part of their independent Protection System with a level alarm on each wellhead separator. Larger volume production wells may need up to four separators per RTU panel.
